Hi All,

While playing with JIT on Suns, I've found out that the following pasm code:

          set   I1, 2
   LOOP:  sub   I1, 1
          if    I1, LOOP
          print "end\n"
          end

never finishes.. that is: parrot -j loop.pasm hangs forever (never printing
'end') while the non-jitted "parrot loop.pasm" prints 'end' and finishes
there as expected.

Can anybody give me some hints as to what is going on there? :)
Thanks,
Stephane

PS.: placing a 'print I1' within the loop resolves the problem, both jitted
and non jitted finishing properly in that case. Instead 'noop', 'set <some>'
or else within the loop dont help the jitted case and hangs again..
